The World of Bunni

Bunni Bunni is a game developed by Andre Spierings and Daniel Cook.
The Bunni world involves building forests and mines and putting bunnies, foxes and even lazy pandas to work. It gets complicated as you have to manage your little ecosystem and feed your workers. The main objective is actually to marry the Bunni girl and fill the island with hearts. There are monsters you will encounter and quests to complete.

Update: The main Bunni Bunni site appears to be no longer active but you can play the game at BubbleBox.
